Subject export/import in hive failing with nested directory exception!
Date Thu, 12 Nov 2015 21:24:22 GMT
Hi,

 

I am doing a simple export and import test from one database in Hive to
another database in the same Hive instance. I thought this would have been
straight forward. 

 

hive> use asehadoop;

OK

Time taken: 0.35 seconds

hive> export table t to '/export/t';
